2200W Pure Sine Inverter/Charger - 24VEVOLUTION(TM) Series Inverter/ChargerPure sine wave inverter, adaptive battery charger, transfer relay - All in ONE unit. Samlex Evolution(TM) Series inverter/chargers provide reliable AC power wherever it's needed. For use with boats, RVs, cabins and specialty vehicles, as well as alternative energy, back-up and emergency power applicationsUsing state-of-the-art technology, the Samlex EVO(TM) inverter/charger operates at 165 million instructions per second with lightening fast load & response times, has 9 points of physical protection monitoring (being scanned up to 10,000 times per second) to detect fault conditions & protect itself in a vast range of adverse environmentsThe EVO-2224 is a 2200 Watt Pure Sine inverter, 24 VDC input, 120 VAC output, 50/60 Hz. It intelligently integrates a 70 Amp 4 stage Battery Charger and a 40 Amp Transfer Relay into an advanced and affordable off-grid power solutionAC InputsTwo separate AC inputs - one for grid (priority #1), one for generator (priority #2), connect simultaneously, no need to reconfigure when different power sources are availableGenerator Input is specifically designed to have more tolerance for wave form distortion, prevents unnecessary "rejection of AC input and switch to inverter" by tolerating distorted wave forms that can be produced by gritty generatorsEach AC input is programmable for voltage and frequency. User determines what the min and max thresholds are to switch from Grid or Generator to InverterGenerator start can be initiated by "Status Relay" contact, can be programmed to activate when grid is lostSolar InputConnect a solar charge controller directly to the EVO(TM) though the Battery Charger external DC Input, seamlessly integrates solar charging into the EVO's power systemONLINE Mode can be used to prioritize Batteries/Inverter over the grid, ideal for those wishing to operate primarily on solar power (when the grid is available, but might be costly)Battery Charger3 or 4 stage charging with Equalization (must be manually initiated)Adaptive algorithm is used during Bulk to assess the condition of the battery. Subsequent stages are then based on the condition of the battery rather than pre-set time periods for Absorption and Float. Prevents unnecessary charging, extends the life of batteriesProgrammable - set battery voltage thresholds to initiate chargingTransfer SwitchZero transfer time when switching from Inverter to Grid. When grid comes on, the inverter synchronizes with the wave form and then transfers instantly at zero crossing
